CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of U.S. patent application Ser. No. 15/594,375, entitled “Protection and Security Mobile Solar-Powered Escalator”, to Daniel E. Guajardo Sr., filed on May 12, 2017, and the specification and claims thereof are incorporated herein by reference.

BACKGROUND OF THE INVENTION Field of the Invention (Technical Field)

Embodiments of the present invention relate to mobile escalators, and more particularly to a solar-powered escalator with safety walls and dome security cover over the escalator for the security, safety, and comfort of the user.

Description of Related Art

When boarding an aircraft from the ground level, open-air stairways leading up to the aircraft door are traditionally used to board passengers. These traditionally truck-mounted mobile stairways (see FIG. 1) can be dangerous and inconvenient for individuals boarding an aircraft. For example, truck-mounted mobile stairways can cause accidents such as tripping or falling and can be dangerous especially in inclement weather. Risks can generally arise from the steep grade of the steps, and the materials and mechanics used to construct the stairway, including inadequate railing, flooring, stability, and so forth. Moreover, known truck-mounted stairways leave passengers boarding an aircraft open to risk and exposed to attacks, for example from snipers shooting from long distances or chemicals or chemical agents.

In particular, the use of such open-air stairways leading up to the aircraft door is particularly dangerous when passengers boarding the aircraft are high-profile individuals or dignitaries, such as the United States President, United States Secretary of State, other heads of state, celebrities, or other individuals that might otherwise be the target of an attack to their person. The safety and security of these individuals is at risk because traditional truck-mounted mobile stairways provide inadequate protection when boarding an aircraft. Additionally, in the case of fossil fuel powered trucks and motors, truck-mounted stairways and escalators have a massive carbon footprint and are generally unfriendly to the environment.

Embodiments of the present invention solve these problems of risk to personal security and environmental concerns. Embodiments of the present invention provide a protection and security self-contained mobile solar-powered escalator system containing an electric cargo vehicle with its own repair and maintenance compartment, an escalator with bulletproof base and security canopy and safety walls accentuating the security and safety of persons boarding an aircraft from the ground level. Embodiments of the present invention provide 360-degree security, external solar panels and interior lighting, hydraulic raise/lower pistons, an exiting platform, and a formal arrival platform. Embodiments of the present invention further proved a driver all-weather compartment with a clear top, leveler and stabilizers, heavy duty front and rear suspension, handrails, repair compartments, optional expandable waterproof and bulletproof entry and exit point coverings, optional interior air conditioning and heating, optional interior and exterior security cameras, a distance light indicator, an inflatable rubber bumper, emergency brakes, optional installments for the physically impaired, e.g., a commercially available stair lift or a wheelchair accommodative escalator combinations thereof, and the like.
